...sexy female version of himself.
He starts to think about how to exactly word the wish, when he remembers Karyn. It probably would be better if she was aware that he made the wish, that way if he messes up somehow she will be able to fix things. Hopefully. Also it wouldn't be a bad idea if he wished to be always aware of what wishes were made, if someone somehow would steal the stone. Those weren't bad precautions in Jon's mind, so he starts wishing.
"I wish that I would always be aware of wishes made with wishing stone as if I heard them and would also know who made the wishes." he says and stone glows brightly, granting his wish.
Next to include Karyn. "I wish that Karyn would be aware about any wishes I do from now until tomorrow morning 8 am, as if she heard them herself." stone glows again
Next the hard part. Hopefully he won't mess up this one. "I wish to become a sexy female version of myself in 5 minutes after I finish this wish and that reality would change as if I was born as a girl. I wish that my previous wish would be only active until I say word: alakazamus, after which reality would adjust itself as if I never made that wish, but my memories would be remained unchanged." Jon sighs in relief as stone glows twice, indicating that both of the wishes were granted. Now he only needed to wait 5 minutes to see his new life.
Those 5 minutes were probably the longest minutes in Jon's entire life. He didn't know how often he glanced at his alarm clock, looking at time and waiting for the wish to be granted. Those minutes seemingly dragged on into forever, one agonizing minute after another. Finally time has come and he felt dizzy, closing his eyes as if something fell into them, the whole room blurring into nothingness as he seemingly zoned out for a minute, not responding to anything.
When Jon opened his eyes again it was as if he appeared into completely different place. The whole room was different. Where the old room could be definitely called boy's room, this new version of the room was definitely girl's room. Thankfully, there weren't pink color. The room was actually painted in light purple and the color and it's various shades seemed to dominate the room and furniture. There was a dresser with some makeup, a large wardrobe with lots of various female clothes, and even a small digital TV with DVD player and movie collection The bed also seemed to be a tad bigger and softer, though it could have been just Jon's mind playing tricks on him.
After looking at room Jon decided to look at himself... though he really couldn't call himself Jon or think of himself as a male... Because she was definitely a girl now.
She looks at the mirror in her dresser, her eyes wide a bit as if she couldn't believe what she was seeing. She was gorgeous. She was a beautiful teenage girl, blossoming into full womanhood, her figure with all the right curves. She had long, straight brown hair that was falling below her shoulders. Her face was beautiful and feminine with perfectly smooth, soft skin and full pink lips. Her chest felt heavy as two large breasts rested on it, currently supported by her black bra. Those had to be D-cup, they looked so large on her soft, feminine body. Her ass was also perfect, it seemed that she had perfect hourglass figure. It was a bit strange to have more extra cushion than she was used to, but it wasn't an unpleasant feeling. Her legs were as perfect as the rest of herself too. After checking that yes - she had female equipment, she concluded that she was 100% female. After that she spent the next minute to just admire her image.
She smiles sexily at her image "Guess I will call myself Jen now..." she muses to herself, admiring her beautiful feminine voice too. She could conclude that her experiment was successful. Anything else could probably wait until morning. It was getting late anyways and she needed rest so she could go to school tomorrow as her new self.
